PRK, or photorefractive keratectomy, is safe for the correction of both low myopia and high amounts of nearsightedness, according to a long-term follow-up study of the procedure. Researchers in Italy followed 31 patients who underwent either unilateral or bilateral PRK in 1991 to 1993. A total of 49 nearsighted eyes were included in the study, and check-ups were performed every two years over a period of 14 years.

Study finds few enhancements needed after wavefront-optimized LASIK and PRK
June 29, 2009A study conducted at Emory University finds the overall rate of re-treatments (“enhancements”) required after wavefront-optimized LASIK and PRK is 6.3 percent. But patients who are farsighted or have at least -1.00 diopter of astigmatism prior to surgery are significantly more likely to need an enhancement.
Night vision may improve after wavefront-optimized laser eye surgery
June 19, 2009People undergoing wavefront-optimized laser eye surgery are more likely to see better at night than to experience a worsening of their night vision after the procedure, according to new research conducted at Emory University. Wavefront-optimized LASIK and PRK use a semi-customized excimer laser treatment designed to control a specific type of higher-order aberration called spherical aberration (SA).
LASIK and PRK found safe, effective for treatment of accommodative esotropia
April 29, 2009LASIK and PRK appear to be safe and effective treatments for children and young adults who have a binocular vision anomaly called accommodative esotropia, according to a recent study conducted by Italian researchers. The findings may change the way surgeons treat certain cases of the eye alignment problem to prevent the development of amblyopia (or “lazy eye”).
Outcomes of LASEK, Epi-LASIK and PRK compared
April 8, 2009LASEK, Epi-LASIK and PRK produce similarly good refractive and visual outcomes when used to correct myopia with a wavefront-guided excimer laser. That’s the finding of researchers at the University of Ottawa Eye Institute in Canada. In the study, 998 eyes with nearsightedness ranging from -1.00 to -8.00 diopters (D) were treated at the university eye center using one of the following laser eye surgery procedures: LASEK, Epi-LASIK, PRK and Epi-PRK.
